Specification of Letters Patent.

Patented Aug. 10, 1920.

Application filed May 29'. 1920. Serial No. 885.113.

"of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Bumpers, of which the following is a specification.

T he present invention relates to bumpers and more particularly to the type designed for attachment tomotor vehicles, an object of this invention being to provide a construction which will be strong and tinrablein use and will at the same time be adapted to absorb a large number of the blows received at the front or the rear of the machine.

To these and other ends the invention consists of certain parts and combinations of parts, all of which will be hereinafter des ribed, the novel features being pointed out in the appended claims.

In the drawings:

Figure 1 is a fragmentary plan view of one side of the bumper;

Fig. 2 is a detail View showing the manner in which an anchoring member is secured to the curved endof aside bar of an automobile; I

Fig. 3 is an enlarged section on the line 3--3, Fig. 1;

l ig. 4 is-a fragmentary rear View of one end of the bumper;

Fig. 5 is .a section on the line 5-5, Fig.

Fig. 6 shows, on a reduced scale a complete bumper attached to} two Side bars.

Referring more particularly to the drawings, 1 indicates the front bar which in this arms 5 and 6 formed of spring metal, these arms being preferably held in the channels by means of bolts 7. The arm 5 is bent outwardly and is secured near the other end of the bumper bar 1 while the arm is bent inwardly and is secured near the center of the bumper bar 1.

Preferably the arm has a loose or sliding connection with the bumper bar 1 and to this end the ends of the bumper bar 1 are turned inwardly at 7 on the rear face of the bumper bar and in spaced relation to the latter so that the outer end of each arm 5 lies between the front portion ofthe bumper bar and the portion 7. In order to permit a free movement between the arm 5 and the v bumper bar the arm 5 is preferably provided with a longitudinally extending slot 8 and a bolt 9 is passed through the slot and' also through the front portion of the bumper bar and the end portion '7 thus holding the end portion against spreading away from the front portion and at the same time confining the end of the arm 5 while permitting relative movement between said arm and the bumper bar 1. The outer end of the arm 6 is preferably loosely secured to the bumper bar 1 by a clip or collar 10.

This construction of a bumper permits of, the inexpensive manufacture thereof, as no large bending appliances are required. Each supporting device embodies two separate warms which are secured to an anchoring piece preferably by bolts which hold the arms firmly clamped to opposite sides of the'anchoring piece. One ofthese arms is' deflected outwardly while the other is reflected inwardly, the inwardly deflected portion being preferably rigidlysecured to the front bar near the center of the latter and the outwardly deflected portion being preferably loosely secured to the front bar near the outer end of the latter, the front bar preferably having its ends bent inwardly on'the rear face ofsuch front bar to cover the ends of the outwardly deflected arms of the supporting means.

What I claim as my invention and desire to secure by Letters Patent is:

1. A bumper comprising a front bar formed of aspring strip with its ends turned inwardly on its rear face, and sup porting means comprising two arms formed of spring stock and each deflected outwardly and secured under the inwardly. turned end of the front bar.

2. A bumper comprising a front bar formed of a spring strip with its ends turned inwardly on its rear face, and supporting means comprising two arms formed of spring portion of the front bar, and supporting means comprising two arms formed of spring stock and each deflected outwardly, each of said arms being provided with a slot near its free end through which the bolt extends, the end of each arm lyiir between an inwardly turned end and the iront portion of the front bar.

4. A bumper comprising a front bar, and supporting means comprising two pairs of arms, each arm being formed of a spring strip, one member of each pair being turned outwardly and being loosely secured to the front bar near the end of the latter, and the other being turned inwardly and being secured to the front bar adjacent the center of the latter.

5. Abumper comprising a front bar, and supporting means comprising two anchoring pieces, each provided with channels on opposite sides, and two pairs of spring arms,

each pair having their inner ends bolted in the channels of an anchoring piece, one member of each bar being deflected outwardly and being secured to the front bar near the end of the Tatter-,:-and the other member of each pair being deflected inwardly and being secured to the frontbar near the center of the latter.
